That's generally my suggestion: Review the complex table and ask yourself whether you haven't essentially fused several simpler tables. If so, break them apart. As Andrew notes, that makes life easier on everyone!

What about the solution of simplifying the complex table into three separate smaller tables? I know the accountants often don't like this but it also makes it easier to see the sections for sighted people as the programs are separated out more clearly. The captions could be "Academic Missions budget allocation 2007-2008" etc and then I suspect we all gain.

In large complex data tables, h<n> tag may help navigation. Screen
reader users may navigate to various segments of the table and then
use regular table navigation to read through details. Header-id markup
cannot be avoided when colspan / rowspan is used to associate data
cells with header cells. The h<n> tag may help one comprehend the
overall table structure. Again the h<n> numbering cannot and must not
be used for column headers  or to group columns. It may be useful for
grouping data rows.
A well written table summary attribute will also help. Sometimes major
sections within the table may also be numbered like:
"I. Operating Expenses"
"II. Administrative and Selling Expenses"
Such numbering helps everyone.
